* Dropped classr.patch; it no longer applies to this version.
* The "configure" script has been renamed to "bootstrap.sh".
* The bootstrapping process generates no Makefile anymore; the build
expression has to call bjam directly to build the libraries.
* Perform build and install phase in one execution of bjam. This is a
lot faster, because bjam won't check the dependencies twice.
